PF3D7_0208500 acyl carrier protein

GFP targeting by mutant ACP transit peptides. (A) Apicoplast targeting of the wild-type ACP leader. (B) Cytosolic targeting of a construct lacking a signal peptide. (C) Secretion to the parasitophorous vacuole of a construct lacking a transit peptide. The substitutions introduced into mutants (D to I) are detailed in the accompanying panels at right (25), where a dot ( ) indicates no change. Check marks indicate putative Hsp70 binding sites. Predictions by the apicoplast protein predictor PlasmoAP are shown for each mutant. Internal labeling in (F) to (I) likely represents GFP in the food vacuole that has been taken up from the parasitophorous vacuole during phagocytosis.
